One would have a difficult time building their own touch screen.
There are a few different touch screen technologies out there. The first (and usually most rugged) is an infrared "grid" that covers the screen. Touching the screen breaks the beams, and that is translated into x and y coordinates.
The more common method is a resistive film that covers the screen. The film has microscopic wires going through it, and when you touch the screen, the wires are shorted together, once again giving x and y coordinates.
A third type (used in the iPhone) is a capacitive touch screen. These are very rugged, however they can't be activated with, say, a pencil eraser like the resistive film.
In the capacitive system, a layer that stores an electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases.
